On that note, bashhist.o did not correctly rebuild when I changed config-top.h either.

top level Makefile.in is missing pathnames.h dependency info for
builtins/evalstring.o and builtins/eval.o.
lib/sh/Makefile.in is still missing a pathnames.h target (see attached patch).

Bash-4.1-rc1 available for FTP
The first release candidate of bash-4.1 is now available with the URL
ftp://ftp.cwru.edu/pub/bash/bash-4.1-rc1.tar.gz
This tar file does not include the formatted documentation (you
should be able to generate it yourself).
This release fixes several outstanding bugs in bash-4.0 and introduces a
number of new features -- a larger number than usual for a minor version
release.
The most notable new features are a dynamic programmable completion
definition framework, a "default" programmable completion option, a
way to pass shell options to subshells, a mechansim to have redirections
allocate and assign a file descriptor to a shell variable, and a way
to direct xtrace output to an arbitrary file descriptor.
`bashbug' may be used to report bugs with this version.
As always, thanks for your help.
Chet
+== CHANGES ==+
This document details the changes between this version, bash-4.1-rc1,
and the previous version, bash-4.1-beta.
1. Changes to Bash
a. Fixed a bug that caused printf to not return a partial value when it
encountered an error while converting an integer argument.
b. Fixed a bug that caused setting one of the compatNN options to not
turn off the others.
c. The (undocumented) --wordexp option is no longer included by default.
d. Fixed a bug in conditional command execution that caused it to not
correctly ignore the exit status under certain circumstances.
e. Added a configure-time check for correctly-working asprintf/snprintf.
f. Fixed some problems with line number calculation and display when sourcing
a file in an interactive shell.
g. Fixed a bug that caused the shell to crash when using `declare -A foo=bar'.
h. Fixed a bug that caused an off-by-one error when calculating the directories
to display with the PROMPT_DIRTRIM option.
2. Changes to Readline
a. Fixed a bug that caused applications using the callback interface to not
react to SIGINT (or other signals) until another character arrived.

This document details the changes between this version, bash-4.1-beta,
and the previous version, bash-4.1-alpha.
1. Changes to Bash
a. Fixed a bug in mapfile that caused the shell to crash if it was passed the
name of an associative array.
b. Fixed a bug that caused the shell to incorrectly split case patterns if
they contained characters in $IFS.
c. Fixed a bug that caused the shell to set $? to the wrong value when using
a construct ending with a variable assignment with set -x enabled and PS4
containing a command substitution.
d. Fixed a bug that caused the shell to read commands incorrectly if an
expansion error occurred under certain conditions in a user-specified
subshell.
e. Fixed a bug that caused the shell to set $? incorrectly if a parse error
occurred in an evaluation context ("eval", trap command, dot script, etc.)
f. Fixed a bug that caused the shell to attempt command substitution
completion within a single-quoted string.
g. Fixed a bug that caused the shell to insert an extra single quote during
word completion.
h. Fixed a bug that caused the shell to crash if invoked with the environment
variable EMACS having a null value.
i. Fixed a bug that caused bash to incorrectly report the presence of new
mail in a `maildir' environment.
j. Fixed a bug that caused the shell to not recognize a here-document ending
delimiter inside a command substitution.
k. Fixed a bug that caused the shell to crash when a a dynamic array variable
was assigned a scalar value.
2. Changes to Readline
3. New Features in Bash
a. The mapfile/readarray builtin no longer stores the commands it invokes via
callbacks in the history list.
b. There is a new `compat40' shopt option.
c. The < and > operators to [[ do string comparisons using the current locale
only if the compatibility level is greater than 40 (set to 41 by default).
4. New Features in Readline

This document details the changes between this version, bash-4.1-alpha,
and the previous version, bash-4.0-release.
1. Changes to Bash
a. Fixed bugs in the parser involving new parsing of the commands contained
in command substitution when the substitution is read.
b. Fixed a bug that caused the shell to dump core when performing programmable
completion using a shell function.
c. Fixed a bug in `mapfile' that caused it to invoke callbacks at the wrong
time.
d. Fixed a bug that caused the shell to dump core when listing jobs in the
`exit' builtin.
e. Fixed several bugs encountered when reading subscripts in associative
array assignments and expansions.
f. Fixed a bug that under some circumstances caused an associative array to
be converted to an indexed array.
g. Fixed a bug that caused syntax errors and SIGINT interrupts
